Why not develop a non-steroidal contraceptive method for men that may be simple as swallowing a pill? It has been discovered that low doses of the same compound that inhibits retinoic acid receptors (RARs) also stops sperm production without any apparent side effects. Once the user stops taking the pill, fertility is restored to normal levels almost immediately.

The idea is to develop a 'camera pill' which will deliver HD videos of the digestive tract in real time. The endoscopic camera will include an HD video camera, light source, radio transmitter, battery, and microprocessor to record and transmit images of the patient's digestive tract. It will also transmit its location within the person's body through the same ultra-wideband waves it will use to transmit the image data.

A new nanocomposite material will be used to fill cavities as well as eliminate any bacteria remaining in the tooth. The material will be made up of silver nanoparticles and calcium phosphate nanoparticles. The silver will kill off any remaining bacteria while the calcium phosphate will help to rebuild the tooth's structure. The dangers of silver nanoparticles are still unknown, and integrating the silver in the material will help to reduce the possible risks of ingestion.

Thanks to a sunscreen we can be in the open sun for a long time and do not get sunburnt. However, even the cream is not a panacea - it can come off, chemically modify and lose the effect. We also often remember to use the sunscreen again when it becomes too late. At the beginning of a hot beach season a special bracelet appears on the market. It allows to monitor the UV quantity obtained and to take actions in time. Doctors and beauticians do not recommend tanning at all as...

The Red Rail Dutch company in collaboration with the Nobel Foundation created the youth fashion collection, which is for donors only. New collection of clothes was presented at the Amsterdam Fashion Week. 18 top designers worked hard to create it. Only people, who donate blood, can get clothes from this collection. The buyers send their IDs, which are assigned to them after blood donating, and name items they would like to purchase. 20 donors will get the clothes from the...

Doorbells for the deaf have been already invented. They usually have a light that flashes brightly instead of playing a tune. What about deaf people who are blind as well... I suggest creating a device which, when activated, uses the only reliable sense left - other than smell and taste - touch. For ex., there can be a vibrating motor in the person's pocket.

Why not provide football helmets with impact sensing accelerometers? This will help to analyze how blows to the head relate to brain injuries. Three types of accelerometers will be placed in the mouthpieces, earpieces, and helmets to see if real time neuroanalysis can occur during the games, allowing for the isolation and diagnosis of the concussions within minutes. By the way, long-term data could provide information on how players become injured and help engineers design a...

Why not use breathable vitamins? They are able to be absorbed more quickly and resist degradation, delivering the active ingredients more efficiently. The vitamins could be ground into tiny particles and packed into an inhaler. The spray of vitamins will be directed upward, rather than down the throat, allowing the vitamins to be absorbed by the tissues lining the cheeks. This method will send the vitamins more directly to the bloodstream and allow for a more potent...

Why not create a nightshirt able to monitor breathing patterns to determine the wearer's stages of sleep? Usually people who suffer from sleep apnea and other disorders must spend the night in a lab hooked up to an array of sensors in order to study their sleep patterns. The new will be much simpler, as well as more comfortable to use, and will be based on the idea that sleep patterns can be detected by monitoring only respiration. The shirt will be embedded with electronics in the...

A new technique of using ultrasound to monitor blood pressure will allow doctors to monitor blood flow in areas besides the arm, which will aid in the diagnosis of vascular diseases. Ultrasound method can non-invasively measure the blood pressure at any point in the body. The ultrasound system uses complex signal processing techniques and a mathematical model to visualize the flow of blood and motion of the vessel walls and determine the blood pressure at a precise location. ...
